1 This invention e ates to 'rei nfef ell ni A special ure.ptinyipr s t inventi is the for ation of wire reve fo icenientskfo ffits; {the 1 reenf ement being farme 9 a plufiali'typf sections of yyireor other suitable material, to be assembled and connected for particular sizes of the assembled re-enforcements within predetermined ranges, for

use.

Pursuant to my invention, the individual ,re-enforcement sections are manufactured in quantity and assembled, usually in pairs,

by Welding such pairs to one another, and/or ried by and spaced by its interconnecting wire.

Preferably, the individual re-enforcement sections are duplicates of one another.

Further features and objects of the invention will be more fully understood from the following detail description and the accompanying drawings,'in which I Fig. 1 is a vertical sectional view through an- I-beam illustrative of a structural element, showing a preferred form of an individual multi-section re-enforcement embodying invention; i

similar to Fig. 1, showing a further modification;

Figs. 6, .7 and 8 are elevational views of further modifications.

In Fig. 1 of the drawings, 10 represents a conventional form of I-beam, aboutits lower flange 10a a soifit of concrete is to be formed.

Pursuant to my invention,th-e re-enforcement is formed of a plurality of sections, usually in pairs. In Fig. 1, the re-enforcement section 11 is paired with the re-enforceme'nt section 12, the sections inijthis instance beingduplicates-of each ii'llefvidual;reienforcementsection of: the. form shoWnin-Fig. 1 is illustrated iniperspes ive on an enlargedscale 5 in Fig. 2, and in detail. comprises; the; body portion, 1:23,: he; spacey portion Li, and the end portion 1 5-..T:1lQIld portion .15 in this; instance-is. pr iomied as a clip toaabut; .an edge iace-ofr the: lr fiilmlfll oth r :istnuctnral ;ele1nent,. its terminal p.01.- tion 16-..beinghent; downwardly nan ang to;locateitsterli illus 1.6a in Contact nith the uppen face Dill 111G low r 915 the ,1- beamilOas appearsin; Eig-111. lots. innenen 1'1.isibent. in..any;desiredangle; aisilal yah a right angle to'the body POM-1011., lSitQlOCQa Q; its terminus.

Such interconnectediorm-of my invention' is advantageous in cratlng -forsh1pment to the location of installh'tiQnf-and facilitates the handling to the individual, multi- Pfairedfreenforceinents in installation.

In the form of my invention illustrated in Fig. 6, the end portions 23 are not preformed, and are adapted to be bent manually by the operative at the time of assembly and installation about an I-beam or other structural element.

Fig. 6 also illustrates the interconnecting by welding at 18 of a plurality ofre-enforcement sections by a plurality of interconnecting wires 19, 19, for the assembly of multiple re-enforcement sections.

In Fig. 7, I have illustrated a further modification, particularly the obverse direction of extension of the inner terminal spacers 24:, 24, in this instance serving as form spacers. A bottom mold board is indicated at 25.

A further variation of arrangement of the individual portions of my re-enforcement sections have an inner spacer 17 engaging at its terminus the lower face of the flange 11 and the form spacer extension 24: extending in the opposite direction, as appears in Fig. 8.

All similar parts of the respective forms of my invention illustrated in the drawings are designated by like reference characters.

The material of the sections is usually of wire, but other metal stock of suitable shapes may be employed.

Whereas, l have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made Without departing from the spirit of the invention.

I claim I 1. A re-enforcement for concrete formed of sections-connected to one another, each section having an inner preformed spacer terminal and an intermediate spacer portion .and a preformed outer terminal portion.

2 A re-enforcement for concrete formed of a plurality of sets of re-enforcement sections, said sections being substantially duplicates of one another, each of said sections having an inner pre-formed spacer terminal and a wire interconnecting said sets to one another.

3. A re-enforcement for concrete formed of a plurality of sets of substantially duplicate re-enforcement sections, each of said sections having a pre-formed outer terminal portion and a pre-formed intermediate spacer portion and a wire interconnecting said sets to one another. 7

4. A re-enforcement for concrete formed of a plurality of sets of re-enforcement sections, each section having a pre-formed outer terminal portion and a pre-formed intermediate spacer portion, and a wire interconnecting said sets to one another.

5. A re-enforcement for concrete formed of a plurality of sets of substantially dupli cate re-enforcement sections, each section having 'a pre-formed outer terminal portion,

formed intermediate spacer portion, one section of each pair having a pre-formed inner spacer terminal and a wire inter-connecting said pairs with one another.

In'testimony whereof I have signed this specification this 19th day of March, 1929. FREDERICK D. KREUDEB.
